Sophia Bailey-Klugh has two dads and one invitation to the White House.

On Monday, the 11-year-old Grant Elementary student and her family — fathers Jonathan Bailey and Triton Klugh and younger sister Ava — will be in Washington, D.C., for the 135th annual White House Easter Egg Roll. There will be a dance party on the South Lawn, food from celebrity chefs and performances by “American Idol” winner Jordin Sparks and San Diego “Idol” runner-up Jessica Sanchez.

Because she is one of 35,000 invited guests, Sophia might not get the chance to meet President Barack Obama. But that’s OK. The girl from Mission Hills and the president of the United States are sort of friends already, and Sophia’s got the letter to prove it.

One Sunday last October, Sophia wrote to the president thanking him for his support of same-sex marriage, especially since some kids at school thought her dads’ relationship was “gross and weird.”

“I thought he would give me good advice and he would be kind about it,” Sophia said of her letter, in which she told the president, “I am so glad you agree that two men can love each other. Because I have two dads and they love each other.”

Like any proud modern parent, Bailey posted the letter on his Facebook page. By the following morning, the paper version was in the mailbox and the online version was blowing up cyberspace. Bailey told his 500 or so Facebook friends and they told their umpteen Facebook friends, and within a day or two, Sophia’s letter was being discussed on the Huffington Post website. And on the CNN and MSNBC websites. And by Perez Hilton.

We’ll let Bailey take the story from there.

“By Wednesday, we got a Facebook message that someone from the first lady’s office wanted our home address,” Bailey said as the family gathered in the living room of the Bailey-Klugh house in south Mission Hills. “On Saturday, the letter from the president came. I Facebooked that, and everything started all over again.”

What did the president say to the girl whose dads have been together for 16 years? Nice things (“I’m honored to have your support and inspired by your compassion.”) Encouraging things (“You are very fortunate to have two parents who care deeply about you.”) Things guaranteed to rile the Web. (“And we recognize that whether you have two dads or one mom what matters above all is the love we show one another.”)

And being that the letter was written while Obama was running for re-election, the Web got itself in a bunch. Some people were convinced the letter was a fake. Others said it was just a cog in the president’s PR machine. Some people thought Sophia’s letter was a fake, while others settled for critiquing her handwriting.

Meanwhile, Bailey (co-founder of the i.d.e.a. branding and marketing firm) and Klugh (vice president of design development for InCharacter Costumes) were fielding interview requests from around the world, all of which they turned down. They were also wondering how a TV producer got Bailey’s cellphone number, why a local news crew suddenly appeared on their front porch during dinner and what in the world they had gotten themselves into.
